- Care must be taken when jacking up and supporting the vehicle. Be sure to lift and support the vehicle at the proper locations.
- PRECOATED PARTS
- Precoated parts are bolts and nuts that are coated with a seal lock adhesive at the factory.
- If a precoated part is retightened, loosened or moved in any way, it must be recoated with the specified adhesive.
- When reusing a precoated part, clean off the old adhesive and dry the part with compressed air. Then apply new seal lock adhesive appropriate to that part.
- Some seal lock agents harden slowly. You may have to wait for the seal lock adhesive to harden.
- GASKETS
- When necessary, use a sealer on gaskets to prevent leaks.
- BOLTS, NUTS AND SCREWS
- Carefully follow all the specifications for tightening torques. Always use a torque wrench.
- FUSES
- When inspecting a fuse, check that the wire of the fuse is not broken.
- When replacing fuses, be sure that the new fuse has the correct amperage rating. Do not exceed the rating or use one with a lower rating.ILLUSTRATION AND ABBREVIATION
